Hi all,
I'm trying to get a TS72XX board working with sparsemem, but got
unlucky so far. I've read all related threads in the archive and
especially this one:
http://marc.info/?l=linux-arm&m=122754446724900&w=2
Here is the patch I've applied:

I have forced some early debugging and dump the meminfo passed by the
bootloader in bootmem_init() (just to be sure of the mem config) and
here is the output i got:

Then I tried digging into the code by following the backtrace, but
couldn't spot anything!
If I force the machine to see only 32MB then it boots fine, I've done
this by passing the mem=stuff on the command line.
I've even tried to force using 2 nodes by over-writing bank->node,
first node for the low part, and second node for the upper part
(0xeX000000) and it boots fine as well, the difference is that the
kernel says that it sees 8 banks of 8MB each, but report only 32MB of
free memory (only node 0 is used I guess).
Obviously, I've missed something, any helps are welcome.
Thanks,
Chris

This seems to suggest that sparsemem is still disabled, since
alloc_bootmem_node will only be called from alloc_node_mem_map
if FLAT_NODE_MEM_MAP is enabled, and this should not be enabled
with sparsemem.
Seeing your .config file might be useful.

So yes, flatmem is still enabled... because there's a condition missing
in mm/Kconfig. Try this patch:
diff --git a/mm/Kconfig b/mm/Kconfig

Sorry if you get this message twice, but time to time, my emails are
rejected by caramon.arm.linux.org.uk because of reverse DNS stuff.
Second time lucky?

Suggest you talk to your mail admin about getting that fixed:
no IP address found for host 133.155.reserved.hosting365.ie
I can't relax this restriction at my end without the machine dying under
todays excessive spam load.

OK, I have to look at this, but it seems actually to happen only if
linux-arm-kernel at lists.infradead.org is in CC, not if it is in TO. For
testing purpose, this email is sent to the list and you are CC.
The previous one was send to you and CC to the ML.
Thanks,
Chris
